A little trick that I learned back in the early 50's, and pass on to
all who don't know of it, is using the PRIMER to keep the engine
running if it shuts down for carb ice. The primer injects fuel
directly into the intake manifold bypassing the carburetor and can
keep the engine running intermittently and in many cases generate
enough heat for the carb heat to become effective again. I've used
this technique a few times in aircraft to get home. In Pipers (PA25
Pawnee while crop dusting) and Cessnas (C-172 and 177).

That's a brilliant suggestion -- I'm assuming that you leave carb heat
on, so that there's still an air supply into the cylinders.


All the best,


David

Carb heat is left on in the event that the generated engine heat
becomes effective again to change the intake air temp.
